i'm really lost on whats wrong on my car. ok symtoms bogs at about 1/3 throtel and then when gives more gas bogs more and startes to sputter and then i here a pop and then it slowly kicks up rpms. now the pops coming form the carb could it be my timming slipping and the spark hitting a lil to quick for the vale to close or i dunno whats going worng any help

 

yeah it could be your timing, why don't you check it and see what it is set at?

 

ok thats probally a good idea so if my timings off that would probally mean my chain is going and is slipping so would it be worth it to replace them with a gear to gear setup or a duble chain setup. and what would be the best advance for a 350

 

Your timing could be off even if your chain is ok. But if it comes to the point that you know your chain is bad, stick with a replacment single or double roller. Stay away from gear driven sets because they can cause false knock that will be picked up by your knock sensor. Not to mention that they sound annoying.

 

thanx that helps alot

 

have you seen those "quiet" gear drives? I think Jackson makes them. They may use angle cut gears. I wonder if they would false trigger the knock sensor?

Regardless, a double roller chain is probably good enough for a daily driver.

 

well i plan on racing in the loacl scca aarf so will double chains still work

 

It depends on how much power and what rpm's your motor reaches. It may be overkill or it may be just right.

 

I would take a single fixed idler setup over a dual "floater" design if i were to go with a gear drive. For the street, a dual chain design will be plenty. For anything that really beats on the the valve train (high rpm) or requires rock solid timing, a gear set is ok.

Ive heard that they CAN trigger due to the harmonics the gears create. However i have heard of people running them without issues.
