Carb tuning, larger accelerator pump nozzle?
How much throttle are you using to get/keep the rpms up as you let out the clutch?
:poke:???
Big difference if your slipping the clutch with the engine at 900 rpm when going into 1st (almost like a truck), to blipping the throttle at a few thousand rpm shifting say 2nd to third enering a freeway.
High Speed Air Bleed: 31 (stock)
Idle Air Bleed Size: 71 (stock). Currently 67.
Primary Main Jet 70(stock). Currently 68 (
Return to 70 for now. Reducing the PMJ too much can can effect the flow to the IFR)
Primary Power Valve 6.5 (stock) (
Probably will want 8.5 but not relevant right now)
Primary Pump Nozzle Size 31(stock) Currently 35
Secondary Main Jet 76 (stock)
IFR 32(stock) Moved to the lower position
E-holes .028 as measured 3 on each side. Top two plugged with set screws on both blocks
(E1-blocked, E2=.028, e3=.028 Yes ?)
Blue front pump cam, stock pink in the secondary. (Probably will end up changing the secondary cam like mderoy suggested. Not relevant yet.)
Timing is 20 degress initial, 34 total. Have not check when it comes in
Need to check the rpms for the timing.
Using a little less initial (17 - 18*) will put a little more heat into the combustion at idle (good thing in this case) but may require letting in a little more air (via the secondaries) to keep the idle rpm high enough it will run. You'll have to refiddle with the primary throttle and idle mix and then the IAB or IFR and IAB. I'd do this next but maybe that's not the best next step for you. Maybe its better to keep working with the current timing and see what changing the t-slot relationship does, then the IAB and so forth. It will give you a better feel for the process (I think).
