Hi RD
Are the Mikuni's fitted at an angle to the horizontal?
This will make setting the float level meaningless as I'm sure you know
It might be that the pilot circuit is being flooded? I would try removing the air screw to see if fuel flows out ?
Is this why racing and steep downdraught carbs have pilot fuel screws rather than air screws ??? I don't know
maybe talking bo**ox

I have read a mikuni with a pilot jet and air screw doesn't like being tipped more than 20 degrees

what have I done with my bike today?? nearly set it on fire *help* *problem* *pull hair out* while waiting for a mikuni pilot jet I decided to fit the monoblock back on. well this caused a problem because I have piped the oil return across from the timing side where the filter is fitted and between the mikuni and cylinder head inlet manifold. with the monoblock being bigger I had to make a 12mm thick ally spacer to set the carb away from the crossover oil return pipe, all well and good up to now. BUT not thinking I hadn't got the bolt on pick up mag on the bike while messing with the gearbox I had dislodged the bottom pick up and hadn't seen this happen. so petrol on-- tickle carb jump on kick start and no go, tickle carb again jump on kickstart and bike starts on one pot. I start to rev the bike thinking I have a triple kwaker and middle pot will jump in shortly but nothing happens , so I look down and see flashes shining off the gearbox . I stop the bike to see what is going on and then discover a drip coming from carb *eek* *eek* thankyou for listening -- tomorrows another day----- got away with that one *whistle*

Hi RD,
I would try two known carbs that work, take them off known running bikes
That will eliminate some unknowns, sort out ignition and other issues and then go back to sorting carb settings

today i stopped the carb drip on the amal  and went for a little  run , she likes the std gearbox back in and I so do I , no whine in 3rd gear *good3* I hope the smaller pilot jet for the mikuni arrives soon because this old amal isn't getting my attention even though it is rich around tick over. played with it many times over the years and it just acts the fool when it wants to *bash*

Berger i feel your pain regards a fire as my pre monobloc dripped onto the mag and did burst in to flames over a year ago and only this week finished sorting it all out and getting it running again.

Motorcycle fires? No problem. Used to have an old 50's Ariel on the farm. Sometimes it would spit back on starting, and set fire to the horsehair under the single saddle. Quick swipe with a cloth used to put it out, ready for the next time.

Today I gathered enough oomph to go and do some work on my bike. Last summer I found that sometimes when I pushed the bike backwards the rear brake would jamb. When I opened up the back brake drum I found that one side of the brake shoe end had broken off and the bit was rattling around doing orrible things to the linings. It's a sobering thought that something like that, especially if on the front brake, could kill you.

I cleaned out all the debris and used the bike until the end of the riding season. I ordered new Ferodo branded shoes from Fecked. Today I took it apart and am just about to fit the new shoes.

I have also ordered a pair of Mitas tyres for the bike today.

I understand that the Isle Of Wight BSA weekend, 18th to 20th September, may go ahead. I'd like to do that if I can.
