DT-90 or DT-100 Oil pump lever stop check

[crappie-attitude]

Please tell me how in the [profane] I'm supposed to measure the gap between the oil pump lever stop and the stopper boss??? For those of you with a Zuki DT-90 or DT-100 manual, it's on page 92.

My seems to have too much oil being injected, which is better than the alternative, but causes excess smoke and smells bad for skiers/tubers being pulled with the boat. So during the off-season, I started to look at reasons and the most reasonable being that the oil-injector lever is set wrong. I can see the tab that is suppose to be a maximum of 1mm, but not touching and can see the boss, but even with a mirror, I can't get anything in there to measure it. Tonight I tried using a 1mm feeler gage as a go/no-go, but I can't even get to the [profane] thing.

Anyone with experience? For those with oil-injection, do you just eye-ball these things or how do you go about it?

Thanks for any input.

Do you see the oil specs in the manual, so much oil flow over time at a certain RPM?
Follow that instruction. I use a medical syringe with ml grads. Remove the oil tank and mount the syringe above the pump and connect. Fill the syringe with oil. Run the motor from a jug of 50:1. Check against the specs. Adjust the connecting rod accordingly untill you have the correct flow rate. I use this method regularly to check and set Suzuki oil rates. I do it every spring on my own motor to be sure it is oiling.
