Sorry to hear about your problems the the Robin engine. I recently purchased a power washer with a 13.5 hp Robin EH41 engine on it. Have only used it for about 3 hours but has run like a champ so far. Hope you experience is not an indication of how they are all built. What is the latest with your situation? 4 months is excessive!

mr, i had to fix it myself,maybe it's better that way.when i got the right parts it runs fine! i had to clean the the carb.it was full of garbage,not bad for 47 hrs. it now has a lot more power,it runs out of traction on a hill, not out of power!
the mower was the next problem, the blades hit the sides of the deck when you are in heavy grass. the deck is only 3/16" thick where the spindels are located is not heavy enough. the old gravely is 3/8" so much for over built! how i found this out was the blades on the deck are 3/8" longer than called for.i called terry about this,it fell on deaf ears. the new blades 16 1/2 and don't hit.a grinder fixed the hitting,but to see where the blades hit is 3/4" above where they are when are not running this is the flexing in the deck, the torque rise when you hit the heavey grass.no wonder the belts don't last. one more thing,by cleaning the carb. it stopped the shut off problem,no more dieseling,i don't have to wait , hit a bump no problem!! /forums/images/graemlins/laugh.gif. and the best for last i fix the seat i now have a suspension for $9.00 , more latter.

mr, this is simple,i used some old 1 1/4" x 3/16" steel to make two u shaped brackets one to fit inside the other.the outer one 9 3/8" wide on the outside,drill two 3/8" holes on 8"centers in each this will match the holes in the mount and the seat. the short ears are 1 1/4 long with 3/8" holes in each.when bolted together the over all height is 2 3/4", drill two more holes in the outside one,this gave me an added adj. for tilt.this makes the hinge for the front.
now the back, tractor supply has coil springs1 1/4 dia. x 4" .148 thick wire buy two,$ 6.00 then two 4"x3/8 bolts and two lock nuts.with tax this should be under $9.00.
now to get something you have to give up something the seat adj. was taken off this will give the extra height i needed, i'm only 5' 9". i sat a small square in front of the seat and marked the position where i have the seat . then i removed the adj. and the front holes lined up,you may have to re drill two of them to get them to line up.then bolt on the hinge
let me back up,now when you drill the front set two 3/8 bolts in the holes now mark the back holes to line up with the holes in the mount drill seat pan. now bolt the hinge on the front , go to the back take one 4" bolt,and put it in the new hole and through mount,screw on the nut finger tight.now pullthe seat away from the mount and put one spring in the other side,slip a bolt down through put on the nut, take the nut off the other side install the spring there.
this first bolt holds the seat together while you put the spring in the other side, just makes things easer.and other thing, i compressed the spring in a vice,it would coil bind at 1 7/8" so i cut two 2" pieces of 1/2" hose two slip over the bolts this will keep the springs from bottoming out.
i don't know how to get a pics on here, it would be a lot easer on my one finger! /forums/images/graemlins/tongue.gif

Off the subject but what mower are you running with your PT-422, is it the 48" or the 60"
