and what is the timing set to???

Roy

Expert:  Roy Belding replied 8 months ago.

no spark timing with a light while cranking.

the compression confirms you have the chain set right

Customer: replied 8 months ago.
spark plug got fire,pour gas straight in carb checked firing order at tdc everything is good.just dosent make sense
Expert:  Roy Belding replied 8 months ago.

ok, what I am getting at is the distributor timing. it needs to be set. you may also have the distributor in backwards and firing on valve overlap

Roy

Customer: replied 8 months ago.
how does that happen, tdc points right at #1,
Expert:  Roy Belding replied 8 months ago.

2 possibilities. it could be on compression or valve overlap.

you need to remove number 1 sprk plug and tap the key until you feel compression out the hole. then hand turn the motor to line up the mark on the balancer and then install the distribuutor.

it does already check it,tdc is right cylinder 1 is at top
Expert:  Roy Belding replied 8 months ago.

I am sorry, you are not understanding me. you need to do a top dead center check and verify the distributor setting.

Customer: replied 8 months ago.
at tdc cylinder is at top,distributor is pointing at #1

New expert here...

I need to ask a couple questions before I can answer this question..

First, you stated that the timing chain was installed using 12 o clock on the crank timing mark and 6 o clock on the cam timing mark. Did you install the distributor with the engine in this position before turning over the engine?

Second, I need to know if you get any spark from the coil when you crank over the engine?

Keep me posted...

Thank you,

Robert

When changing the timing chain didn't work, I then changed the distributor,i plulled a spark plug and turned it over and i get spark,i check tdc,cyclender #1 is at top,dist is pointing at the #1 wire,getting fuel
Expert:  Robert R replied 8 months ago.

When you checked #1 TDC, did you remove the #1 spark plug and put your finger over the hole while turning the engine to see if you get pressure buildup as the #1 piston is reaching TDC? We need to verify that number 1 is actually on the compression stroke and not #6.

The reason that I asked the above questions is because when the timing chain is installed with the crank gear at 12 o clock and the cam gear at 6 o clock, it is actually #6 TDC and NOT #1. Number one TDC requires BOTH the crank sprocket AND the cam sprocket to be at the 12 o clock position. If this is the case, your distributor is installed 180 degrees off. If you remove the distributor and rotate it 180 degrees and reinstall it, I suspect that you WILL get the engine started...

Try this and let me know if it helps you get the engine started....

Keep me posted and let me know if you have any additional questions...

Thank you,

Robert
