timing

I came across this explanation on the workings of vacuum advance on The"B Bodies Only" website. It's authored by "Revhendo" and I found it worth sharing. For those of you interested....... This was written by a former GM engineer as a response to a similar question on a Camaro board: As...

Hey all. So I have a 79 camaro, 350, HEI distributor. I just finished assembling the motor and wiring and when I'm trying to start it, it just keeps cranking and seems to spit puffs of gas out of the carb. To me it sounds like the cam and crank timing is out of whack and unfortunately I didn't...

Hello, i have a truck with an unknown cam in it. also i don't have a timing tab installed. I'm having problems with a hot start. I'm pretty sure that the timing is really advanced in order for the engine to run smooth. the problem occurs after its good and hot. then the starter will crank...

Hello, So im working on a Hyundai 1.6 SOHC (09 Accent, 95000km) that developed a knock that increases with RPM and seems to be louder when in gear. Sounds like it is coming from the front of the engine. -Did the screwdriver listening test to all cylinders without much change. -Have lifted the...

I screwed up the timing on my machine. I got it fixed, however the seam is now biased towards the bottom, like the top thread is too loose or bobbin thread is too tight. I cranked a couple of turns more tension on the top thread, which didn't seem to change anything. Is there anything I could...

Last week my 84 corvette would not start. I had a friend come over and verify that it did not jump timing. So I changed the ignition module and the coil. Turned out to be the coil, so I left bot brand new parts in the car. Then I drove it about 100 miles. Ran better than it ever ran. The...

2004 Chevrolet 350, when coming to a full stop or backing up it sounds exactly like a diesel engine, pinging and rattling and shaking. Anyone heard of anything like that? My mechanic was stumped.

I have a 383 sbc stroker. Summit k1103 cam, I sethe timing to 32 degrees and it ran beautiful for a year. Put it on the dyno and did a pull and then it idels but when you go and take off or pull out it studders and sometimes pops out the carb but once its at 20mph it hauls. Checked timing it was...

Hey everyone. Back again with another probably simple fix. It would appear that I am getting very light preignition.. the weird thing is i can't hear anything except for when i'm at part throttle cruise. Every time I check my plugs, if I look deep down inside on the porcelain and inside...

Hello everyone: I'm back again with more issues! Just scratching my head over this whole delema and I'm about out of ideas. I'm having a hard time trying to find the root of this problem. Basically the title says it all... it has a small miss every so often at part throttle cruise. Changed...

I recently had a machine shop in OKC rebuild my 350 small block for my 1936 Chevy streetrod. They chose Speed Pro CS-1014R Camshaft for this application. Engine rebuild was non-eventful as well as re-installation. The engine parts additional info is this: GM Factory HEI ignition Hydraulic...

So I'm about to finally get to cranking my motor up and setting timing here soon. I've got a Holley 4160 carburetor at 650CFM and I adjusted my transfer slots (which were way off) as suggested on this forum and plan to get my mixture screws adjusted to max vacuum once timing is set. Anyway, My...

Need help with this one. 62 Ford 352. Starts and runs fine for about 20 seconds then runs really bad and feels like timing is out. Disconnected and plugged vacuum advance. After warming up it smooths out on its own and the engine runs fine. Timing is dead on and running smooth when warm. When I...

Hey guys, I recently acquired a 67 Nova that was set up for the track, and I am in the process of making it more streetable. It has a Barry Grant 800 Carb on it. Right now the jets in it have been bumped up to I believe 78. I have been searching to find specs on my carb to find what the stock...
