do her by ear for now. as for the light. double check all your connections for good contact. might make sure the light is hooked up the right way (some have an arrow to show the direction the spark should be moving through the wire) hook directly to the battery. If all else fails, make sure your ALT is putting out enough voltage while it's running. if that doesn't work I suggest dynamite for the light.

 

ok so i stepped up and spent a little on a timing light 40 bucks and walla it worked. i have come to the conclusion that it was 2 bad lights one by number of uses and the other by cheap manufactoring. now that i got it working onward to the rough idle and in drive idle rpms i so need a tach and thanks for all the help ive been driving the truck I did the first timing by ear

 

Tachs are on sale at summit racing.44 bucks

 

Awesome!!! That's what my gut feel was all along. Glad you got that prt licked. Usually pay for it in the end if you don't buy quality tools.

 

Better tools,better job

 

well iam aim the timing to be at 12 degree and iam trying to figure out this whole idle speed i have to idle it high to get it to stay stamble once in gear? is this normal for the i6

 

and how much is that tach on sale for

 

No that is not normal. should probably idle around 750 in park and 600 in drive.

You sure you got the timing right? How did you set the initial timing?

Make sure the vacuum advance is disconnected and the vacuum source is capped. Set it to spec, probably around 7 or 8 degrees btdc. Then reconnect the vacuum line and set the idle

 

i did some r and r today yes i disconnected the vac advance and caped it i dont have a tach just yet so iam unsure if it is trully jumpen a bunch from idle to in drive but it sounds like it is to me could be fan noise though iam unsure. i know that at idle it is smooth but high were it sets when in drive is a little rough shakes the truck just a tad anylower and things get jiggly. Ive worked on tons of chevy so i know that setting the timeing is all and all the same just different numbers that and those were v8 not inline iam planning on getting a tach but due to me getting married next week every penny is going towards that. After setting the timing at 11 maybe 12 degree it is running really strong pulls hard for a 6 i know that these are low rpm torqy motors

 

I did check the timing before i changed anything to see how close my ear got it i was setting at 1 degree advance!!!! not bad i dont think

 

any suggestions towards the intake and exhaust ive noticed that part of some of the intake runner flanges were they bolt up are broke

 

I've never had a I6 in one of theses. There ate some guys on here that are total experts on those babies.
I would recommend searching for the threads on that...I've seen several on just that...300 intake and exhaust options. If you don't find what you're looking for...start a new thread...one of those experts will find you

Sorry I'm not much help there...but would rather get you to an expert than just guess

 

Check the inline 6 forum [down the page]!

 

ok so ive ran a day or too at 12 degree advance base and have run into a rough cold start it has to turn over alot before it fire and once it does fire it will stumble alot and die is this a comen thing with the i 6 or is their a underlying problem some where else???? carb???? could it need adjusted again???? i plan to recheck the timing and makesure no timing shift has occured. once she is hot she runs good a little partial throttle acceleration but drives good>......

 

being advanced that much may make it more difficult to start. try backing it off a couple degrees and see if that helps.

Also sounds like your choke needs to be adjusted.
