How to set timing on my Chevy 305 car?
-What year is your Chevy?-What model is your Chevy?-How many miles are on your Chevy?-What type of engine is in your Chevy?-What have you already tried?
1985 but after market motor
g3 van in a motor home
I have already tried to set timing by standred means
Recently had a tune up dne to our 85 chevy 305 had great compression and power prior to tune up, and some hole repaired between manifold and pipe, now no power or compression acts like bad timing, but when you turn the distributor gets worse instead of better. we are fund raaisers and the motor is in our motor home which is our full time home need to try to fix this and get back on the road if you can please help
When you say there's no compression, have you checked with an actual compression guage?
Did this happen immedialty after the tune up? If so what parts were replaced in the tune?
Cap rotor wires plugs and then it turned out that he said and has set the timing, but turns out that the cap was not tight when he did this and now the motor runs like its junk and yes it happened RIGHT after he was done
when the motor is running it back fires and sputters when you idle it runs good but when you put in gear it starts the sputters and back fires
again no power when you try to go. You can get it up in speed with a good run but takes a while and wont climb hills for anything
No I am guessing I am not a expert here but dont have the money to go to the shop and have to get form NC to FL or PA
Alright, sounds to me like it's possible the plug wires were not put back onto the distributor cap correctly, this not only makes the engine run really bad, if at all...but greatly affects the timming. See the firing order below...it's very important that the wires are on the cap in the right order, and going in the correct direction. The black dot represents cylinder number 1, and the firing order follows in the clockwise fashion.
Double, and tripple check the firing order until you know 100% that it's correct, this is the #1 reason for this problem after the cap and rotor are replaced. If that looks good than i've also posted the timming procedures below - you need a timming light.
IGNITION TIMING PROCEDURE
NOTE: Timed at number 1 cylinder with 4 wire Electronic Spark Timing connector, at distributor, disconnected.CAUTION: Always check the underhood emissions label (if available). Specifications and procedures on the underhood emissions label supercede all others.
