1 bbl. vs. 2 bbl. carbs

[snailwagon]

As many cruiser owners admit, they would like a little more power. The only options that I have considered to achieve this is a late 70's fully electronic LC ignition and possibly a 2bbl carb to replace my 1 bbl. Is there much of a power/response gain by doing this swap, or is it a waste of time? My one barrel actually runs pretty good and can basically run while vertical or very sideways as long as the tank is picking up fuel. My pig is a 1969, the carb I was considering is an early 70's non-USA 2bbl. Thoughts, opinions? Webers are out of the question, this is a 4x4, not a VW bug. Fuel injection is more involved electronicaly and financially than I would like to go at the moment.

if the carb is correct for 69 its not a 1 barrel, 68 I think was the last year for those, but who knows. the 69 aisin 2 barrel is suppose to be the worst AIsin made.

I LOVE the 1 barel AIsin carbs, I run one on my 45 with a 77 2F motor. Last year I swaped to the fully electonic ignition and dizzy, WOW, HUGE improvement. So thats what I would do 1st, see if you happy or not, if not then go to the 2 barrel carb

Don't listen to him. He has no experience.

It's an early 1969 (november 1968), and I don't trust anyone with over 3900 posts.

and for sure don't trust anyone that happens to have a press photo of a 67/68 fj55

or someone who has the parts books for a 67/8 fj55

yes the 1 barrel was used on early 55's

Swap to an 81-87 2F ignition with ignitoer/coil. Best ign. toyota made.

You've got a good carb and dizzy combo. Make sure your dizzy is getting full dwell 38-41 degrees, rather than relying on point gap. Power time the dizzy with tips from the thread on setting timing, and LEAVE IT ALONE!

In the choice between the never-ending search for power,
versus longevity, I choose longevity!
