Hi,
I'm running a pertronix unit of measurement along with a superstock accel curlicue. The benefactor is turned completely in towards the block (fully advanced, I believe). When using a timing light on it, the mark is way off the caste scale; however, whenever I endeavor to bring the timing down the engine gets rough and stumbles. I bypassed the resistor wire and so that shouldn't exist an issue. Is the engine just going to be happy with the timing that far avant-garde? Or are there other things I tin cheque?

Thank you for the help

The timing marker on your crankshaft vibration damper has probably slipped. This is quite common on Ford engines. To see if information technology has, bring the piston on #1 cylinder all the style to the top ( TDC ). Look at the mark on the pulley and the scale on the encompass. You lot should see " 0 ". If it is not, just take a white marker and draw a thin marker on the caster that lines up with " 0 ". Now you can gear up your timing to specs. Be aware with the garbage gas nosotros take now, that factory specs may non requite you the best performance and economy! I would set the timing to spec, drive the car, move the timing 2° advanced and drive the motorcar once more. If it is ameliorate, continue advancing it 2° at a time. If it ran worse advancing the timing, do the aforementioned thing ( starting at spec ) just retard the timing two° at a time. We may have to go back to distributors that y'all can set from within the car if the fuel gets much worse! I am using alcohol free fuel in my car correct now ( I merely got 5 gallons ) to exam information technology and then far I've noticed better starting, ameliorate running, and better mileage! It is $i more than regular gas ( funny how not putting something in there costs more than ), simply I think the mileage makes up for nigh of it. I'd use 100LL avgas, but information technology is $five.46 a gallon here!

Would it skid within only 300 miles on a new engine? and to put the piston TDC, just plug the #1 plug and look?

It can admittedly slip in 300 miles! If you have air conditioning, each time the compressor cycles will permit it slip as well! I marked mine to fix timing and checked information technology after a few days and it had moved over ten°! Yep, I know I demand a new pulley, only I'll wait until I come across the piddling rubber ring going bad get-go.
To set TDC, aye, only remove the spark plug and turn the engine past mitt with a wrench on the caster nut. If you polish a calorie-free into the spark plug pigsty, it will be very easy to run across when the piston is all the way to the pinnacle! Once you go it to the acme plough the engine slightly back and along. You'll be able to tell when it'due south right at the top!

Never ran the ac since it needs a new compressor ha. Guess information technology's good to know it can slip that much. I know when we starting time installed everything, the mark was however of the scale. So maybe information technology was installed a molar off?

Make certain y'all're checking the timing with the vacuum line asunder and plugged. If not, so yous will get very high readings. I use a drinking harbinger from McDonalds to observe TBC. Be certain the engine is cold or the straw will melt.

I can't imagine the timing is besides far off as of at present. I'thousand getting 18 mpg highway and temp is staying correct at 190 on a hot day. Don't know if that'south indicative of anything.

You lot should be getting around 23-25 mpg with a 200

Yes, I would kickoff with all the basics. Check TDC and the timing marker, gear up the spark plug gap to the electronic ignition specs , make certain the Pertronix unit of measurement is gapped properly (they have a gap spec just like points). Check vacuum lines (I had a bad distributor modulator valve that really played havoc with me but I eventually showed um whose boss)
I also had issues with my spark plug wires, the Accel and Pertronix will cutting through OEM wires and will make your engine bay expect like Christmas all night long. I've included a few links beneath, the have smashing data on the half dozen's, specs, troubleshooting etc…

Once you lot have double checked the basics, get back to u.s.a. and permit us know how it went!

I usually put in premium here (forgot what that is, maybe 91?). The engine is a fresh rebuild equally well with the 2bbl progressive weber. So non sure what to expect with fuel economy. My automobile does start right up. A bit cold blooded until the electric choke warms up. I know since we first fired the engine the timing mark was off the scale

No. It's going through adaptor plates. No shop here would touch it.

Have a 1970 200 ci with ten,000 original miles...getting engine ping when I step a little harder on the gas or going up a loma. Set the timing to factory specs — same outcome. I've been moving the distributor a tiny bit, driving information technology, moving it again when I hear the pinging. The pinging all the same happens. I've disconnected the 2 vacuum lines and plugged them and information technology all the same pings. I'one thousand using 89 octane gas. I presume the pinging can injure the motor at some indicate. Any suggestions. Thanks! Whatever Maverick experts in the Rhode Island area?
