I'm guessing your comment above to me in post #17 was meant for MikeG. MikeG said what is shown below, but you messed up the cutting and pasting in the quote process and it looks like I said it. I've done it several times when quoting, but usually catch it. Actually, I usually delete most of what I respond to and go get some work done. lol

I've cleared obstructions before in different vehicles by completly choking the carburetor off with your hand with the engine running with a few revs up...it don't always work ...but its worth a go...

Cowboy tune up

Make sure your battery is fully charged, and replace the orings and gaskets on the intake stubs , and all is flat .

My problem is, I usually think most other people know as much as myself. When I ride my motorcycle, I know immediately if it is jetted too rich or too lean, from what it does. It comes from a mispent childhood.
If the motor is sluggish, it is too rich. If it misses, it is too lean, or has an electrical problem.
If your bike accelerates much faster in really cold weather, it is probably jetted too rich for normal weather.

To my mind when a cylinder / plug is running black then there is either an excess of fuel and or oil ……. or …..
there is a lack of spark.

If the plug looks clean then surely it has to be a lack of fuel.

8 stroking ? Well if only one cylinder fires properly and the other not or just occasionally then that may well imitate the 8 stroke effect ?

Rectum noise ? Maybe ? Just how it seems to me.

Mine started to run funny after having tank off , it was just off idle 1 ½ cylinders , i found my cable wasnt happy where i had it, and it had gone out of sync , rerouted cable and synced , sounds better already .

That plug looks to be white on ground strap? Over lean?

When you checked carbs, did you get a good spray of cleaner/wd40 etc up through the idle jets in carb air filter end of throat floor, before/after throttle slide?

What is mix screw at compared to good side?

How is condition, sealing of the inlet manifold balance pipe?

One jet assembly dropped down into the bowl last summer for me . Now that was one rich running carb until club help 150 Kms. away towards home .

Operator states it runs better with a cold engine.

KiwiShane · Jul 2, 2023

As we know removing the air filter will upset/change the fuel to air ratio... making the engine run slightly leaner and possibly ?..better/worse when it gets to full operating temperature ...I'd be stripping that carb and doing a full orifice examination

Using vacuum from the engine and my fat hand on twin choke side draft Dellorto's
Outboard motors and the like..all with success...dont under estimate a lawn mower carburetors potential...

So we can look forward to either a twin side draft or down draft , mower carb conversion on your commando soon

, think of the miles per gallon ! .

and ease of cleaning. Actually I've done the hand on carb thing heaps , engine vac to suck the shit out , works good .

I'm very happy with the Keihen's thanks

A old army engineer mate of mine stuck a twin choke side draft on his 920 years ago...it run real well ...he had some jewelers drill bits to tune in his jetting as bits for them at the time were hard to get hold of.

Issue was electrical. Its an Old Britts Power Arc ignition, which calls for resistor wires and plugs. One wire showed far more resistance than the other. The one with low resistance was the side that was skipping and looked too lean.

re filling a car's gas tank is NO way to measure fuel burned. If he had done it with a calibrated one gallon can and run it until it was out of gas it would have been more precise.

I posted the video to show with a few modifications you can get a lawn mower carb to make a V8 run...I'd prefer a 4 barrel to do that job.. and I took no notice of any claim of fuel economy or efficiency
