Late to the party, sorry. Over revving usually means an air leak, so...Change O rings on starter, Carby, and two on the inlet manifold (with one O ring, you need to take the manifold off the engine block by unscrewing both mounting screws). Make sure the venturi connection on the engine block is free of gunk, the end hose of the carby connects to this, as the vacuum can be affected if it is blocked and it will rev almost to the moon, so try pushing some wire back and forwards through the little pipe there. Also make sure that hose is clear. Make sure there aren't any leaks in the snorkel hose or through the filter housing itself; crimp the hose in various sections (with your hand) to see if the revs lower when you do. Try placing a small brass washer or two under the carby lifter. Last of all, if none of the above works, try putting the poppet valve in on the "B" position rather than the "C" position. You can even try "A" if you like. C is leanest mix, followed by B setting, and A is the richest setting. Good luck (if you are still fixing it).
im having this issue, done the carb seals, cleaned everything, only thing i havent done is engine seals but if i disconnect air hose from filter it lowers rev a tiny bit
@@mudzy9820 Try following the advice I gave above, in order of ease. Over revving is too much air, or loss of vaccuum. Rarely, it can be fuel starvation, but this usually cuts the engine (or stops it from even starting).
Like already said it will most likely be an air leak somewhere. Greg gregson mentioned everything to check. If for any reason it still playing up after all those things (which will solve 90% of the time) you can try to fit a small washer onto the carburettor body under the cam plate. Sometimes the cam plate can wear down over time and the engine behaves its got an air leak, but its not. so the washer is to push it up very slightly
Watch Victa 2 stroke carburettor adjusting videos here on utube this will fix your proplem there's a a b and C adjustment in carburettor you watch videos here n you will get it where you want it to run ok cheers
Conquer that’s a two stroke should be able to adjust the fuel mixture and back off an idle and that should be OK but I’ve never seen a motor look like that before
Nice video Phil, on that carb does it have any check valves in it, sometimes if the check valves go bad of get damaged it'll cause the high revving. And hey, you're looking good brother.
man where are the on off wires that go into the carby. they must have made different carbys for over seas models. i have 6 victa 2 stroke mowers there fantastic
Gd luck Phil sorry I can't help but a interesting video IV had a Briggs for 20 years it's not run for last ten problem was it was working I went to work my son cut the grass I tried week later it revs it bits of so just got put away
Well you have my attention on this one I've never seen one like that really different ! Hope you get it sorted and please document it I'm really curious. Usually high revving engines is governor related 🤷 Also that spring looks really long but hey it came out of there absolutely stumped !

Good job Phil and congrats for going over 300 subscribers sir!👍🇺🇸🇬🇧

Great video mate hope you're well
you can add brass washers/shims CR03619A buy from dc spares these take revs down.
Keep up the good work you’ll get it Phil

Interesting carb, I haven't seen one of those before

Odd looking carb, not seen one like that before. I’m sure you’ll get the issue sorted.

Yes a pressure tester would identify your issue.
did you sort it out mate
Where can I buy this repair kit
i know you will fixit phil
Where have you been hiding Stumpy? 🙂
@@Big_Johns I’m back John been so busy sir hope your well
Yes sir I am, just checking on you, busy is good though. 👍
