225 2 stroke cranks but won't fire

[Baysidejim]

I'm not much of a Motorhead so any information would be greatly appreciated. The motor started and ran great the day I bought the boat. Went to start it today and no luck. It turns over. Kill lanyard is connected. Prime bulb is full. What do I check next? Thanks!

Don't know what model you have, but, does it need to use the choke/primer (if it has one) usually activated by pushing in on the key?

[Baysidejim]

The choke is not activated by pushing the key in as normal but with a toggle switch right under the key.

[pstephens46]

And what would be the model number of this motor?

[ausnoelm]

OK, I think the toggle switch model is a normal old butterfly choke? (But I could be wrong) are you using the choke while turning over the motor? are you lifting the warm up/high idle lever while trying to start?

[Baysidejim]

Yes the lever is lifted. I turn the motor over for about a second then hit the choke. I've had a few 200 horsepower 2 stroke Mercury outboards and a couple older 150 Johnson's and that's how I always started them. That's how I started this the one time that it ran. Model number of the V6EXCELXF. Thanks for the help!

You have a 1989 engine with carbs and butterfly choke assemblies (no prime start):

Pull the cowl off, and see if the choke linkage is moving when you activate the choke switch.

Once that's working,
on a cold start, try a slightly higher idle but choke it from the start..

That motor also has sensors....TPS, CPS,KS. might want to check values on them.

I've experienced a kill switch issue before where the "key" was slightly cracked. Because of that, it wouldn't pull the kill switch "pin" out far enough. Possibly this is happening with you, or the key is worn. Try manually pulling the pin out fully.

I assume that the kill switch cuts spark on your engine... you can also check by seeing if you have spark at the engine (check a plug). It would good to know if you have spark, regardless, as that is one of the 3 main components of fire.

I had the same model.
There is a manual pull out choke button on the front of the lower engine cowling port side.

Thanks. The choke is working when I pull the toggle lever up. I did try the manual choke also. I'm waiting for a neighbor or somebody to turn the key so I can check to see if there is spark. Thanks very much everybody much appreciated.

pull the stop lanyard. crank it.
audible should sound.
if it does the kill circuit and alarm work.
if it does not find the audible issue as well.

Thanks, I'm not sure what those are or "check Values" means.

Thanks,
Just did that and no alarm...

[Baysidejim]

Choke is working. It has spark.
